4. Lead from a king or queen, rather than from an ace. For since the adversaries will lead from those suits which you do not, your ace will do them most harm.
5. Lead from a king rather than from a queen, and from a queen rather than a knave. For the stronger the suit, the less is your partner endangered.
6. Lead not from ace-queen, or ace-knave, till necessary. For if that suit be led by the adversaries, you have a good chance of making two tricks in it.
7- In all sequences to a queen, knave, or ten, begin with the highest. Because it will frequently distress your left-hand adversary.
8. Having ace, king, and knave, lead the king. For if strong in trumps, you may wait the return of that suit, and finesse the knave.
9. Having ace, king, and one small card, lead the small one. For by this lead your partner has a chance to make the knave.
10. Having ace, king, and two or three small cards, play ace and king if weak, but a small card if strong in trumps. For when strong in trumps, you may give your partner the chance of making the first trick.
11. Having king, queen, and one small card, play the small one. For your partner has an equal chance to win, and you need not fear to make king or queen.
12. Having king, queen, and two or three small cards, lead a small card if strong, and the king if weak in trumps. For strength in trumps entitles you to play a backward gamey and gives your partner the chance of winning the first trick; but if weak in trumps, lead the king or queen to secure a trick in that suit.
